JOSEPH It. BROWN, OF BRIDGEPORT, CONNECTICUT, ASSIGNCR TO THE AUTOMATICFIRE EXTINGUISHER COMPANY, OF NEW YORK, N. Y.

AUTOMATIC FIRE EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 306,316, dated October7, 1884.

Application filed April 7, 1883.

To all whom it may concern:

Be it known that I, JOSEPH R. BROWN, of Bridgeport, county of Fairfield,State of Connecticut, have invented a new and useful Improvement inAutomatic Fire-Extinguishers, and I hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, formingpart of this specification.

My invention relates to that class of fireextinguishers in which thedischarge of the liquid is prevented by a fusible joint, except in theevent of fire.

My invention consists in the combination, with the extinguisl1er-body,of certain peculiar and novel devices for confining the liquid withinthe extinguisher, and for discharging and distributing the same whendischarged, as hereinafter described and claimed.

Figure 1 is a side view of my improved automatic fire-extinguisher; andFig. 2 is a similar View of the same, partly in section.

In the drawings, A is the inlet to the extinguisher, which is dividedinto two branches, B and B.

I) is the discharge-outlet, and c a sheet-metal disk closing the branchB. The outlet 1) is closed by the cap D, provided with the stem, whichis secured by a solder fusible at a low temperature in the cup E, theclosed end of which is provided with a screwstem entering the nut F,which rests on the deflector 0. By this arrangement the cap D is firmlyforced against the outlet 1), and when the extinguisher is subjected tointernal pressure the same is exerted on the deflector c as well as onthe cap D, and is thus balanced. Vhen, now, on the breaking out of afire the solder melts, the stem of the cap D is forced into the cup E,the force of the water removes the same, and the stream meets theyielding deflector c, by which it is dispersed in all directions. Thebranches B B are arranged as shown, in order that their outer ends maylie opposite to each other, and thereby the parts D, E, and F shall bein'alignment and between the outer (No model.)

ends of the branches. A suitable packing is interposed between the cap Dand the outlet 1), and the nut F is not permanently secured to thediaphragm 0, but simply rests thereon,

the said diaphragm being provided with a central boss or projection,which extends upward somewhat into the nut F, and thus prevents The diskor diaphragm 0 is made of thin sheet metal, so that when theextinguisher is in operation the liquid by its internal pressure in thebranch B will spring the plate or diaphragm variably, and the liquidfrom the opening b,falling upon this moving diaphragm, will be deflectedvariably, and will thus act effectively upon the burning mass.

I-Iavingthus described my invention, I claim as new and desire to secureby Letters Patent 1. In an automatic fire extinguisher, the combination,with the extinguisher-body having a discharge-opening and adeflector-seat oppositely disposed, of a deflector permanently seated inthe deflector-seat, a valve seated in the discharge-opening, andconnections, sub stantially as described, united by fusible solder andinterposed between the valve and the deflector, and operating in themanner specifled.

2. The combination, with the body composed of the branches B B, andhaving the inlet A, of the solder b, the deflector c, the cap D, the cupE, and the nut F, all arranged to operate substantially as set forth.
